> Project: Calcite

> {code:java}
> RexBuilder.makeIn(inputRef(0), ImmutableList.of(literal(100)))
> {code}
> Current behavior:
> {noformat}
> SEARCH($0, Sarg[100])
> {noformat}
> Proposed behavior:
> {noformat}
> =($0, 100)
> {noformat}
> The EQUALS operator is simpler than the SEARCH operator and it is handled
> better by other components. Although, the SEARCH to EQUALS transformation is
> already something that is done during simplification not every piece of code
> calls the simplifier.
> This basic simplification could also be done directly inside the makeIn
> method when the caller passes a single point value.
